Application filed November 5, 1907.

Patented Dec. 8, 1908.

Serial No. 400,876.

Ho all whom it may concern:

Be it known that l, CLAUDE Siinnwoon, a citizen of the United States,residing at Black lear, in the county of Shoshone and State of Idaho,have invented new and use- 'tul Improvements in Ore ConcentratingTables. of wh'ch the following is a specification.

This invention relates to ore concentrating tables. and particularly toan attachment to etlect in a` rapid and thorough manner proper gradingor separation of metallic values without possibility of their subsequentaccidental mixtures, waste, or the necessity of changing the adjustmentor set of the table. ythe ataclnnent may be employed with advantage inconnection with various types of tables. but is of especial utility whenused in connection with an endwise reciprocatory. transversely inclinedtable.

in the drawings: Figure l is a perspective view of a concentrating tableprovided with an attachment en'ibodying my invention. Fig. Q is a topplan view oit' the attachment detached from the table. one of thevalves, hereinafter particularly described, being separated from saidattachment and in perspective. Fig. 3 is a view of the attachment asseen from the table, two of the troughs thereof being` in section. Figs.t and 5 are cross-sectional views on the lines tft and respectively, ofFig. 2.

Like characters refer to like parts throughout the several figures ofthe drawing.

ln Fig. l a table of known type is shown and generally designated by thenumeral 2, and is transversely inclined and given an endwise orlongitudinally vibratory or reciprocatory motion by any suitable meansfor the purpose of stratifying the pulp supplied thereto. rfhis tablehas on its upper side .longitudinally disposed ritiles with theirt'orward ends arranged in step order or are upon a line extendingdiagonally of the table so as to leave a clear space, as ft. along whichthe lead separated from the pulp on the motion of the table is fed, thelead, when it leaves the table, falling into an inclined trough 5secured to the head end of the table in any suitable manner. Thist-rough is one feature of the improvement and directs the lead deliveredthereinto into any suitable receptacle. The other feature of the.improvement is designated in a` general way by G and comprises severaltroughs, hereinafter more particularly described.

ln addition to troughs, the member G includes an inner row of connectedpockets 7 of any desirable number and disposed along the lower side ofthe table Q connnencing at the head ond and extending toward the tailend of said table. lnto these pockets lead and zinc middlings and otherconstituents are delivered and disposed of by means within the controlof an attendant, as will be hereinafter made clear. The pockets orcompartments may be made in one piece of any desirable metal or othersuitable material, and while they may be of any shape they arerepresented as being substantially square. llach pocket 7 is shown ashaving countersunk in the bottom thereof a disk valve S provided with apivot t). 'lhe several valves S are operated by diaimtrcally oppositehandles S connected thereto and are held in their adjusted positionspreferably by friction. By countersinking the valves in the bottoms ofthe respective pockets or parti* tions 7, said bottoms will not presenton their upper surfaces any projections or protrusions upon or againstwhich mineral values or the like might lodge or catch. In the bottom ofeach pocket or compartment 7 are three holes l0, ll and l2. Each rotarydisk valve S has through it a single hole or perforation 13 adapted toregister with any one of the three holes or openings l0, 1l or 12 in thebottom of its respective pocket or compartment 7 for a purpose that willhereinafter appear.

In addition to the inner series of pockets 7 there is a second or outerseries of pockets 7, and these pockets 7iL may be of any number; forinstance, if thirteen of the pockets 7 are provided, four of the pockets7a would be preferably used. The numbers of the two series of pocketsare simply mentioned, however, by way ot' illustration and will dependsomewhat upon the size of the table and dimensions of the pockets. Thepockets 7L are constructed like the pockets 7 in all particulars,including the bottom openings, but to avoid confusion and facilitate anunderstanding of the apparatus, the openings in the pockets 7 aredesignated by the characters 7 7C and 7, respectively, the pockets TfLcontaining valves S each provided with a single opening` 8" andoperating and constructed exactly like the valves 8. The pockets 7a arecoincident with the lirst four of the pockets 7, by virtue of which thefirst four pockets 7 can discharge respectively into the pockets 7a. Theprimary purpose of the pockets 7"L is to provide for the proper disposalof the iron that passes over the lower side of the table near the frontend thereof, although these pockets can be used to dispose of the Zincor lead which may be therein by manipulating the valves 8. The valve 8of each pocket 7 will be turned to register the opening 13 of the valvewith the openings 10, 11 and 12 in accordance with the character of thematerial. owing into the several pockets, and if Zinc flows into thepockets the opening 18 of the valve 8 will be caused to register withthe opening 10; if middlings of Zinc and lead are directed into thepockets the openings 13 of each valve will be placed in registrationwith the openings 11, and if tailings flow into the pockets the openings13 of the valves will be caused to register with the openings 12. inother words, the several valves 8 will be positioned to relieve thepockets of their contents in relation to the several troughs inaccordance with the particular character of the material flowing intothe pockets from the table. The registration of the opening 13 with anyone of the bottom openings 10, 11 and 12 will result in a closure of theremaining two openings. It is the custom to return the middlings backonto the table to be worked over, while the tailings can be deposited ina heap and also worked over at desired intervals.

Practically the same operation may be effected in the pockets 72l asabove noted or when materials of different kinds solely occupy theselatter pockets and under this condition of sole occupation of thepockets when the opening 8b of each valve 8a registers with the opening7d, this is for the purpose of directing zinc through said opening 7d.Then the opening Sb in said valve 8a registers with the opening 7b, thisis for the purpose of permitting lead to pass through said opening 7b,and when the opening in said valve 8a registers with the opening 7C,this is for the purpose of causing iron to pass through said opening 7C.By the manipulation, therefore, of the several valves or any one or moreof them, the proper grading of the values and other materials that passoff the table can be obtained.

The member 6 is provided with four longitudinally extending troughs 14,15, 16 and 17 the trough 14 being adapted to receive the pure Zinc, thetrough 15 the zinc and lead middlings, the trough 16 the tailings, andthe trough 17 the iron. The trough 14C discharges the mass within itforwardly or toward the head end of the table; the trough 16 dischargesthe tailings therein toward the rear or tail end of the table; thetrough 15- discharges into the middlings elevator, not shown, and therear end of said latter trough is represented as somewhat deflected orinwardly disposed for this purpose, and the trough 17 causes thedelivery of the iron in a forward and slightly lateral direction. Thefour troughs and the trough 5 hereinbefore described are separated fromeach other in a watertight manner so as to prevent possibility ofmixture of the materials therein, and the said troughs may be disposedin cooperative relation to the pockets 7 and 7 a of the attachment inany desirable manner.

From the under side of the openings 10 in all the pockets 7, except thefirst four of the latter, spouts 10a project for the delivery of zincwhich may pass through said openings 10 into the Zinc trough 14. Whenthe openings 13 of the several valves 8 register with the openings 11 ofthe pockets 7, lead middlings will be directed into the trough 15. Thenthe openings 13 of said valves S register with the openings 12, thetailings will be delivered into the trough 16. Vhen the openings 13 ofthe valves 8, except the first four thereof, register with the openings10, zinc will be directed by way of the spouts 10il into the trough 14,and when the openings 13 of the first four valves S register with theopenings 10, the contents of said first four pockets 7 will be directedinto the companion or outer pockets 7 a. The materials delivered intothe outer pockets 7 a will, therefore, be released and recovered inaccordance with the positions of the valves 8a. Should the opening 8b inone or all. of the valves Sa register with a cooperating opening oropenings 7d, zinc will be directed from the pocket or pockets 7 a intothe trough 14. Should the opening Sb in any one of said valves 8aregister with the cooperating opening 7 b, lead will be delivered fromthe first four pockets into the trough 5, said trough 5 having anangular extension 5a, as shown in Fig. 2, which extends under theseveral openings 7 b. Should the openings in the four valves 8"11register respectively with the openings 7", this will be for the purposeof directing iron into the trough 17. Therefore, by the manipulation ofthe several valves the constituents discharged from the table may beseparately recovered or properly graded. Should the valves St1 be setfor effecting the discharge of iron into the trough 17, and should it beseen by an attendant that Zinc or lead is being delivered into thepockets 7 "L, such latter materialscan be directed into the propertroughs by a simple manipulation of the valves SZL without changing theadjustment or set of the table, witlrrespect to the pockets 7 and thevalves S.

From the foregoing description relating to the discharge of theindividual materials t or substances through the outlets et' the pockets7 and 7a and into the several troughs mentioned, it is not to beunderstood that ditferent materials are simultaneously liberated fromeach pocket, but that when one kind ot material is flowing into eachpocket, that material may be liberated into the proper trough Which hasbeen devised for the purpose.
